Three U.S. Army soldiers were onboard a BlackHawk helicopter that collided with a passenger jet near Ronald Reagan Washington National Airport, U.S. officials said on Wednesday.

Pilot Alan Montoya and co-pilot Jesús Juárez were at the controls of the Learjet 55 as they flew a young girl , who had just received “life-saving care” from a Philadelphia hospital, and her mother home to Mexico, according to the outlet Milenio.
